In 2013, HLDI evaluated changes in teenage driver exposure for calendar years 2006–12. This analysis updates the previous study to include 2013 & 2014. Nationally, teen exposure increased in both years while prime-age exposure continued to decline slightly. Results are consistent with the hypothesis that economic factors play an important role in teen exposure. (Vol. 32, No. 30 | December 2015)

The purpose of this analysis is to explore the extent to which collision claim frequencies vary by vehicle size and type for 15–17-year-old drivers relative to 35–50-year-old drivers. Thirty-two different vehicle size and type groups were examined and, in all but one, claim frequencies were higher for young teens than for prime-age drivers. (Vol. 31, No. 4 | April 2014)

The level of insured teenagers has declined between 2006 and 2012. Results suggest that a key factor in the decline has been the recession and the extremely high levels of teen unemployment. Graduated driver licensing laws were shown not to have had a large impact on the recent decline. (Vol. 30, No. 17 | September 2013)

The purpose of this study is to determine if collision claim frequencies for 16- to 19-year-old drivers relative to 35- to 60-year-old drivers vary by vehicle type. Crash rates have been found to vary by vehicle type, size, and weight within a group of similar type. This analysis shows that some of the crash rate differences are amplified for teen drivers compared with prime age drivers. (Vol. 28, No. 7 | September 2011)
